Opinions about management of geriatric syndromes given by internal medicine residents in two programs.

Internal medicine residents in two programs providing different amounts of training in geriatrics were surveyed in 1988 regarding their opinions about the management of four geriatric problems and two traditional internal medicine problems. The residents generally agreed that geriatric problems were legitimate concerns in a general internal medicine practice but demonstrated less confidence in the management of geriatric problems than in the management of traditional problems. Residents from the program that provided more extensive training in geriatrics evidenced greater support for nondiscriminatory care of elderly diabetics; otherwise there was no convincing evidence of differences between the two programs. The authors conclude that educational efforts in geriatrics need to target trainees' confidence in the management of geriatric problems.

The validity of proxy-generated scores as measures of patient health status.

This study examines the validity of proxy assessments as substitutes for patient assessments of patient physical and psychosocial health status. Data were obtained from 275 patient-proxy pairs who were enrolled in a national study of Adult Day Health Care. Patients and proxies (informal caregivers such as spouses) were asked to complete the Sickness Impact Profile (SIP) based on the patients health status. Findings showed that patient-generated and proxy-generated physical scores were highly correlated, although proxies rated patients as slightly more impaired than the patient's rated themselves. The correlation between psychosocial scores was not high enough to consider proxy responses as valid substitutes for patient responses. We explored these differences in response by comparing regression equations predicting patient-generated and proxy-generated physical and psychosocial SIP dimension scores. Variance in the patient-generated psychosocial score was explained by physical function, psychological distress, cognitive status and patient age. Proxy-generated psychosocial scores were primarily explained by the caregiver's psychological distress and perceived burden. These findings point out the importance of considering the source of patient health status estimates when interpreting the results of research studies.

Abnormal eating attitudes and body image in older undernourished individuals.

An anorexia nervosa-like syndrome has been reported in older persons. To gain additional insight into this condition, a questionnaire designed to assess the severity of eating disorders (the EAT-26) was administered to 183 male outpatients. Thirty-four subjects were found to be undernourished by midarm circumference measurement and 21 by weight adjusted for age-sex-height. Approximately 60% of malnourished subjects acknowledged inappropriate self-control around food, up to 26% described other unsuitable eating attitudes, and 3% to 52% evidenced various forms of distorted body image. They scored high on EAT-26 Oral Control subscale but low to normal on Dieting and Bulimia and Food Preoccupation subscales. These results indicate that abnormal eating attitudes and body image occur in an important minority of undernourished elderly males, but the pattern of abnormalities differs from that seen in classical anorexia nervosa. This association deserves additional investigation, with special attention to the psychopathology producing high Oral Control responses and to females as well as males. In the meantime, clinicians need to consider anorexia-like attitudes when caring for malnourished seniors.

Medicare reimbursement for geriatric assessment: report of the American Geriatrics Society Ad Hoc Committee on Geriatrics Assessment.

This ad hoc committee report from the American Geriatrics Society proposes the prompt initiation of Medicare reimbursement for geriatric assessment (GA) services (also termed comprehensive geriatric assessment or geriatric evaluation and management services). Despite an extensive body of literature documenting the effectiveness of GA for improving health care outcomes in many settings for identifiable groups of frail elderly patients, no explicit Medicare reimbursement mechanisms currently exist to cover GA services provided by either hospital or physician. We believe that new physician reimbursement codes specific for geriatric assessment should be established in the Current Procedural Technology (CPT-4) manual and that reimbursement for GA should be specifically provided under Part B of Medicare. Further, we believe that hospital reimbursement within the Medicare prospective payment system should be modified to encourage GA during inpatient stays for appropriate patients. This paper summarizes the background for these recommendations. It defines the major content of GA at three levels of intensity--screening, intermediate, and comprehensive. It describes the major sites for conducting GA--hospital, office, home, nursing home. Finally, it proposes criteria for targeting patients most likely to benefit from GA.

Impacts of geriatric evaluation and management programs on defined outcomes: overview of the evidence.

Comprehensive geriatric assessment is a technique for multidimensional diagnosis of frail elderly people with the purpose of planning and/or delivering medical, psychosocial, and rehabilitative care. When comprehensive geriatric assessment is coupled with some therapy, then the term geriatric evaluation and management (GEM) will be used. Following a brief history of comprehensive geriatric assessment, we describe the varied patterns of GEM program organization and review the literature of studies examining GEM effectiveness. Program diversity complicates drawing firm conclusions about GEM effects; however, the vast majority of studies report positive, if not uniformly significant, results. Our analysis suggests that much of the variability in findings is due to sample size limitations. In order to reach conclusions of program effects across studies and to avoid problems of small sample sizes, we undertook a formal meta-analysis. In this initial meta-analysis, we sought to evaluate the effect of GEM programs on a single outcome: mortality. We pooled all published GEM controlled trials into four major groups: inpatient consultation services, inpatient GEM units, home assessment services, and outpatient GEM programs. Meta-analysis of 6-month mortality demonstrates a 39% reduction of mortality for inpatient consultation services (odds ratio 0.61, 95% confidence interval 0.46-0.81, P = 0.0008) and a 37% reduction of mortality for inpatient GEM units (odds ratio 0.63, 95% CI 0.42-0.93, P = 0.02). Home assessment services reduced mortality by 29% (odds ratio 0.71, 95% CI 0.55-0.90, P = 0.005). On the other hand, no significant survival effect was found for outpatient GEM programs (odds ratio 0.96, 95% confidence interval 0.61-1.49).(ABSTRACT TRUNCATED AT 250 WORDS)

Working group recommendations: targeting criteria for geriatric evaluation and management research.

To maximize the cost effectiveness of geriatric evaluation and management (GEM) programs, criteria need to be established for selecting patients most likely to benefit. A working group was convened to define appropriate patient selection (targeting) criteria for each type of GEM program and to consider research questions for future targeting studies. The group outlined targeting criteria for the spectrum of GEM program types and locations. GEM program types included: inpatient GEM units; hospital geriatric consultation service; GEM programs in nursing homes; outpatient GEM programs for functionally impaired persons; and geriatric community outreach/screening programs for functionally independent elders. For each program type, the group outlined targeting criteria based on current literature and experience. Because research has not yet established the effectiveness of many of these patient targeting strategies, the group drafted a set of research questions, pertinent to targeting, that require attention: (1) For each identifiable population of elderly people, who are most likely to benefit from GEM? (2) How should these people best be identified/targeted? (3) What criteria should be used for targeting? (4) How and how often should population screening be performed to identify persons in need of GEM?

Geriatric home health care. Conceptual and demographic considerations.

This article has explored conceptual and demographic aspects of HHC and the distinction between formal and informal care. HHC for elderly persons is shown to be mainly an informal, familial activity with important formal professional, skilled, and unskilled components. Formal home health care in the United States has undergone a historic transformation with the rise of third-party payment as a principal, defining force and with demographic and epidemiologic transition of the general population. Recent national studies demonstrate that the principal population group receiving HHC services--the chronically ill, functionally limited, noninstitutionalized elderly--is growing in number and as a proportion of the group with home and community service needs. Although diverse formal service innovations are being explored to meet these growing needs, current involvement of medical professionals in formal HHC emphasizes relatively short-term, post-acute therapeutic and restorative care offered through Medicare-certified home health agencies.

Home safety and fall prevention.

In conclusion, the majority, or at least a large proportion, of accidental injuries in the elderly are preventable with careful medical and environmental evaluation and intervention. A vigorous diagnostic, therapeutic, and preventive approach is appropriate in all older patients who fall in addition to those at a high risk of falling. Any intervention that can make inroads on this major cause of death and disability in the elderly population will clearly have major impact.

The value of assessing falls in an elderly population. A randomized clinical trial.

OBJECTIVE: To measure the effects of a specialized postfall assessment intended to detect causes and underlying risk factors for falls, and to recommend preventive and therapeutic interventions. DESIGN: Randomized, controlled trial. SETTING: A long-term residential care facility for elderly persons. SUBJECTS: Within 7 days of a fall, 160 ambulatory subjects (mean age, 87 years) were randomly assigned to receive either a comprehensive postfall assessment (intervention group, n = 79) or usual care (control group, n = 81). INTERVENTION: The postfall assessment included a detailed physical examination and environmental assessment by a nurse practitioner; laboratory tests; electrocardiogram; and 24-hour Holter monitoring. Probable cause or causes for the fall, identified risk factors, and therapeutic recommendations were given to the patient's primary physician. MEASUREMENTS AND MAIN RESULTS: Through use of the assessment, many remediable problems (for example, weakness, environmental hazards, orthostatic hypotension, drug side effects, gait dysfunction) were detected. At the end of the 2-year follow-up period, the intervention group had 26% fewer hospitalizations (P less than 0.05) and a 52% reduction in hospital days (P less than 0.01) compared with controls. Patients in the intervention group had 9% fewer falls and 17% fewer deaths than controls by 2 years, but these trends were not statistically significant. CONCLUSIONS: Our study suggests that falls are a marker of underlying disorders easily identifiable by a careful postfall assessment, which in turn can reduce disability and costs.

Formal geriatric assessment instruments and the care of older general medical outpatients.

To improve identification of cognitive, affective, gait, and nutritional problems in older medical outpatients, non-physician clinic personnel administered formal geriatric assessment tools to 183 medical outpatients age 70 years and older. Definite impairments were demonstrated in 7% to 23% of patients (depending on the function being assessed), and borderline abnormal results were common as well. Overall, 56% of patients had at least one meaningful impairment identified. Few of these problems had been recognized before the survey. Assessment required 10 to 15 minutes of interviewer time per patient (approximately 22 minutes for each problem newly uncovered). A simple education and information intervention led to physicians addressing the newly identified problem in 30% to 55% of cases. These results suggest that formal geriatric assessment instruments provide an efficient mechanism for case finding in older medical outpatients. Further studies are necessary to determine whether such interventions will lead to improved outcomes in older medical outpatients.

Oral diseases in older adults.

In the case presented, a 65-year-old man with multiple dental, medical, and social problems benefited from interdisciplinary assessment and treatment. Despite his poor oral-health status and oral-health behaviors upon admission, patient education and dental therapy resulted in improved daily oral hygiene, elimination of oral diseases, and improved oral function. The overall quality of life of any individual, particularly an older one, can be enhanced through oral-disease prevention, health promotion, and, when indicated, dental therapy. This patient was treated in a hospital environment with a well-established team approach to geriatric care. However, regardless of the care setting, the physician can play a key role in improving the oral health status and quality of life of older adults by including an oral screening examination as part of the periodic comprehensive geriatric assessment, recognizing oral pathology, requesting dental consultations and encouraging appropriate dental service utilization.

Growth of the teaching nursing home. The Veterans Administration experience.

Nursing homes are becoming increasingly involved with medical education, and the Veterans Administration (VA) has been particularly active in this movement. We conducted a system-wide survey of VA nursing home facilities to determine the degree to which they participate in medical and other professional training and the features associated with such training. Of the 116 VA nursing homes in 1987, 113 (97.4%) returned completed questionnaires. Compared to "standard" VA facilities (n = 85), "teaching" nursing homes (n = 28)--those in which physicians received at least 20 hours of training per capita annually--were significantly larger, admitted and discharged significantly more patients per occupied bed, and placed a significantly larger proportion of discharged patients in noninstitutional community settings. Care costs in the teaching nursing homes were slightly but not significantly higher, despite significant increases in levels of professional staffing and amounts of training activities in all disciplines. During the survey year, teaching nursing homes provided training experiences for 440 students, residents, and fellows in internal and rehabilitation medicine, as well as for 2,700 other health professionals. The growth of teaching nursing homes in the VA system appears to be associated with positive changes in the pattern of health-care delivery, and it is increasing the number of health-care professionals trained in long-term care.

Comprehensive geriatric assessment: toward understanding its efficacy.

Comprehensive geriatric assessment (CGA) offers health care professionals a technique for multidimensional diagnosis of frail elderly people to plan medical, psychosocial, and rehabilitative care. In the present paper, we provide a brief history of geriatric assessment, a description of the varied organization of geriatric assessment programs (GAPs), and a review of published effectiveness studies of programs worldwide performing comprehensive geriatric assessment. Program diversity has complicated drawing conclusions about the efficacy of CGA from a literature reporting generally positive, but not uniformly significant, results. We suggest that sample size limitations explain much of the variability in findings. Using the techniques of meta-analysis, we evaluate the effect of GAPs on mortality when all controlled trials are considered cumulatively. Meta-analysis of six-month mortality demonstrates a statistically significant 36% reduction of mortality for inpatient CGA programs (odds ratio = 0.64; 95% confidence interval = 0.50 to 0.83), and a 32% mortality reduction for all CGA programs (odds ratio = 0.68; 95% confidence interval = 0.57 to 0.80). Further use of meta-analytic techniques can be employed to clarify the effect of GAPs on other important outcomes (e.g., reduced hospital and nursing home use, improved functional status), and to identify program characteristics best promoting these benefits.
